Frequently Asked Questions

What is burn rate?

Burn rate is how fast a company spends cash. Gross burn = total monthly expenses. Net burn = expenses minus revenue. Example: $120k expenses, $50k revenue = $70k net burn. Track monthly and aim for 18+ month runway before fundraising.

What is a good burn rate?

Good burn depends on growth and funding stage. Benchmark: burn should be justified by growth. If burning $100k/month, ARR should grow $300k+/month. Rule: Growth Rate % should be 3-5x Burn Multiple. Maintain 12+ month runway minimum.
